Separations of mixtures would be a physical change because you are not changing the chemical make-up of the mixture. Instead, you are simply sorting parts of the mixture. For example, taking out all of the blue blocks in a bag full of red, yellow, green, and blue blocks would be an example of a physical change and separating a mixture.
